'''Point Blue Conservation Science''', founded as the '''Point Reyes Bird Observatory (PRBO)''', is a California
-based wildlife conservation and research non-profit
organization. PRBO was founded in 1965 to study bird migration along the Pacific flyway
, and has the longest running population study of landbirds in North America west of the Mississippi river (continuous since 1966) located in Marin County, north of San Francisco, as well as maintaining a year-round research presence on the Farallon Islands
since 1969. PRBO is headquartered in Petaluma, California
with several active field research stations and sites throughout California. Their field station in Bolinas, Ca offers environmental education, guided tours of the mist-netting process used to study birds, and seasonal interns are there all year learning about banding/studying birds. In June 2013, the organization changed its name to Point Blue Conservation Science.
